MOORING DEVICE.

Application led February This invention relates generally to mooringdevice, the invention having more particular reference to a novel typeof extension device for boat anchors.

This invention has for an object the provision of an improved mooringdevice which will prevent the boat anchored thereto from shipping waterduring a heavy sea, or in rough weather, and to prevent the rope frombeing under heavy tension which usually causes the plank of the boat toopen up.

A further object of the invention is to provide an extension device ofnovel construction and arrangement of parts, hereinafter more fullydescribed, claimed, and illustrated in the accompanying drawings, inwhich- Fig. 1 shows a boat anchored with my improved device attached tothe anchor line, as it would appear when in use.

Fig. 2 shows an enlarged vertical central sectional view of my improveddevice.

Fig. 3 shows a longitudinal sectional view taken on the line 3-3 of Fig.2.

As here embodied my improved mooring device comprises a vertical tube10, preferably of brass, or any non-corrosive metal. The adjustable stop11, of cylindrical shape, and similar material, is a slidable fit in thevertical tube 10, and has a plurality of longitudinal centrally locatedapertures 12 to accommodate the bolt 13, or any similar suitable meansof attaching the stop 11 to the vertical tube 10, it being understoodthat the bolt 18 may be passed through any desired one of theheretobefore mentioned apertures 12, for the purpose as will behereinafter set forth.

The upper vertical rod 14 has attached, by threads, or any similarsuitable method, at its lower extremity a disc 15, a slidable fit in thevertical tube 10. The said upper vertical rod 14 extends beyond theupper extremity of the mooring buoy, and is bent, formed, or hasattached thereto a suitable eye 16 to which the mooring rope 17, chainor any other suitable flexible member is attached.

The cushion 18, of cylindrical shape, preferably of rubber or anysimilar resilient material, a slidable fit in the vertical tube 10, isalso threadedly attached to the lower eX- tremity of the upper verticalrod 14, directly 4, 1926. serial No. 85,891.

rial is superimposed between the cushion 18 and the upper cap 20, and islocated in the vertical tube 10, so as to normally hold the uppervertical rod 14, in the position as clearly shown in Fig. 2, of theaccompanying drawing.

The lower vertical rod 21, the disc 22, the eye 23, to which the anchorrope 24, chain or any suitable flexible member is attached, the cushion25, the lower coil spring 26, and the lower cap 27, are similarlyarranged and located, as the above mentioned similar named and describedparts.

The mooring device body comprises an upper member 28, and a lower member29, of hollow construction, preferably stamped or pressed non-corrosivemetal, preferably pear shaped, and rigidly attached to one another, asat 30, by any suitable rolled seam, as is ordinarily used for joiningsheet metal tanks, and the like. The upper member 28, and the lowermember 29, have bent, or otherwise formed therein a groove 31, suitablylocated to receive the rim 32 of the heretobefore mentioned upper cap20, and lower cap 27, which are threadedly attached to the extremitiesof the heretobefore mentioned vertical tube 10.

It being understood that the joint formed at the grooves 32, will becoated with any suitable water proof cement or the like to preventleakage of water into my improved device.

It will be further understood, that the upper cap 20, and the lower cap27, are provided 'with packing nuts 33, by means of which the packing34, may be forced against the upper vertical rod 14, and the lowervertical rod 21, to prevent leakage of water into the vertical tube 10.

It will .be also understood that the eye 16 of the upper vertical rod14, and the eye 23 of the lower vertical rod 21, are attached to eachother by means of the chains and 36, or any suitable flexible members,of sufficient free length, to allow the said upper vertical rod 14 andthe said lower vertical rod, to be extended.

It will be also understood that the heretobefore mentioned bolt 13 maybe placed in any desired one of the heretobefore mentioned apertures 12,so as to increase the stroke of one piston while decreasing the strokeof the other. The piston having the greater stroke will thus be morefree to move against its expanded spring and will accordingly take upthe tension on the rope attached thereto without causing the otherpiston to be moved. rIhis relation will exist only up to a certain limitwhen equal compression is present in both springs and under suchconditions both pistons will be equally affected by tension in theropes.

Referring in particular to Fig. 1 of the accompanying drawing, it willbe understood, that the heretobefore mentioned mooring rope 17 isattached to the boat to be anchored, as designated by the referencenumeral 37, and that the heretobefore mentioned anchor rope 2i, will beattached to an anchor, as designated by the reference numeral 38.

It is obvious that the boat, moored to my improved device, in a. heavysea, or the like, will extend the upper vertical rod 14 and the lowervertical rod 2l, and will therefore ride the waves.

IVliile I have above described the preferred form, construction, andarrangement of the several elements employed, it will be understood thatthe device is, nevertheless, susceptible of considerable modificationtherein, and I therefore reserve the privilege of resorting to all suchchanges as may be fairly embodied within the spirit and scope of theinvention as claimed.

Having thus described my invention what I claim as new and desire toprotect by Letters Patent of the United States is as follows:

1. In a device of the class described, a vertical tube, an uppervertical rod and a lower vertical rod disposed in said tube, said rodshaving attached thereto at one of their extremities discs slidablyfitting in said vertical tube, a stop attached at the center of the saidvertical tube, springs interposed between the said disc and theextremity of the said vertical tube, as a means of holding the said rodsin a normally unextended position, a water tight casing surrounding saidvertical tube having openings at the ends thereof to accommodate theends of said tube, and sealing caps disposed in the ends of said tubehaving openings therein adapted to provide water tight fittings for saidvertical rods.

2. A mooring device comprising a vertical tube, an upper member and alower member attached to each other substantially enclosing said tube,a. groove formed at the upper extremity of the said upper member, and asimilar groove formed at the lower extremity of the said lower member,to receive caps threadedly attached to the extremities of said verticaltube, an upper vertical rod and a lower vertical rod, having discsattached thereto, slidably fitting in the said vertical tube, springslocated in the said vertical tube and interposed between the said discsand the said caps, so as to normally hold the said discs against a stopattached to the center of the said vertical tube, and a means ofadjusting the said stop.

3. A mooring device comprising an outer sectional casing having openupper and lower ends, a vertical tube positioned centrally in saidcasing having its extremities disposed in said openings, a stopadjustably secured intermediate the extremities of said tube, pistonsdisposed in said tube adjacent opposite ends of said stop, springsengaging said pistons normally holding the latter against said stop,rods attached to said pistons and extending outside of said casing, saidrods being adapted to be attached to mooring ropes, said rods andpistons being movable in opposite directions to provide in a resilientlyextensible tension absorber, and water tight sealing means disposed inthe ends of said tube adapted to permit the passage of said rodstherethrough.

In testimony whereof I have affixed my signature,

EMIL PETERSEN.
